I disagree (but I don't think your comment is worthy of downvotes). For instance, you and your hypothetical school-age children know the most about relative teacher quality within their schools outside of the schools themselves. Presumably, relative quality should be proportional to relative pay. Many people call asking us[1] to list only positions and salaries and leave the names out, but without having the names of employees, there's no way for you to see how effectively your tax dollars are getting spent in the ways that affect you the most. The only real harm done is to the ability of the government to underpay people. There's also the embarrassment some people feel when their friends and family find out their salary, but given a job title, you can guess someone's salary with sufficient accuracy.
Tools like this allow citizens to find out if exceptional employees receive relatively exceptional pay, and if certain positions are over- or underpaid in general. There is actual virtue in these tools, though admittedly most of our hits probably come from the salaciousness factor.
